We use a combination of epoxy resins specifically designed for the use in the timber window repair and restoration work, and are used extensively on local authority and English Heritage projects. Basically this means when we bond a window section in place that is where it stays with no movement or cracking of the joint line.

The timber type and quality used to create the sliding sash window repairs is of utmost importance, we only use grade 1 European oak for all cill and window repairs .

We stick behind the quality of our components and workmanship and offer a five year guarantee on all our repair work and draught proofing systems, no small print no exceptions, if anything goes wrong we put it right at our cost.

Over a period of time sash windows can succumb to the adverse effects of the British weather causing the timbers to rot away. The normal areas that decay first are the sill sections and the bottom of the boxes , also the bottom sash rails and horizontal glazing bars are prone to rot.

The south elevation of properties are most at risk of decay due to the southern sunshine, this has a worse effect on woodwork than rain by causing the paint and wood to split and crack leading to water ingress and eventually wood decay.

Most rotten window sections can be restored with our sash window restoration process, by either cutting out the rotten sections and replacing with new timbers bonded on with Repair Care two pack epoxy resin especially designed for the restoration of woodwork, as they are extremely tough and stay permanently elastic to allow for expansion and contraction in the timbers they bond to. Or we may fill the missing section completely with Repair Care epoxy resin if the area is not too large.
